Comment(by feranick@…):

 Gwyddion 2.29 is out. It's still in version 2.26 in macports (as per this
 bug report) and it should be updated to the latest.

 Gwyddion 2.29 - Changelog

 Application

     Translations updated: Czech, French, Russian.

 Libraries

     libgwyprocess: New function to calculate grain-wise rms.
     libgwymodule: gwy_file_get_data_info() sets its arguments to NULL if
 no file info is found, fixing a possible crash if newly generated data are
 saved.
     libgwyapp: Recent file names are compared canonicalized, fixing
 repetition of the same file in document history on MS Windows.

 Modules

     Pixmap: Scalebar ticks and label can be enabled/disabled.
     Grain statistics: Displays total projected boundary length.
     Median line correction: Masking is supported.
     TIA SER: Spectral data import is supported.
     Statistical quantities: New quantity was added: grain-wise rms.
     Omicron: Files created by SPIP are recognised and loaded.
     Nanoscope: Support for old files without @2:Z scale was improved.
     Object synthesis: A bug causing Critical warning/crash during the
 generation of non-square data was fixed.
     Seiko: The guesswork involved in loading of non-square files was
 somewhat improved.
     Neural network: Result model size can differ from source,
 miscallaneous small improvements.

 Other

     Standalone python gwy module is available (experimental).
     Several icons were improved.
